REFRIGERATOR ATTACHMENT.

SPECIFICATION forming part of' Letters Patent No. 696,645, dated April1, 1902.

Application filed July 11,1901.

To all whom, t 17u14/ concern,.-

Be it known that I, ALEXANDER B. Konsa- NOT, a citizen of the UnitedStates, residing at New Orleans, in the parish of Orleans and State ofLouisiana, have invented a new and' useful Refrigerator Attachment, ofwhich the following is a specification.

The present invention relates to machines for holding the tribes ofrefrigerating barrels or receptacles while the former are beinginsertedinto or removed from said barrels or receptacles.

The invention is especially designed for use in connection with a novelconstruction of refrigerator described and claimed in a copendingapplication filed October 7, 1901, Serial No. 77,894, and a divisionalapplication of this case.

While no claims are made for the refrigerator per se in the presentapplication, in order that a clear understanding may be had theconstruction of said receptacle and its relation to the machine areshown in the accompanying drawings and described in the followingspecification. Y

The object of this invention is to provide a machine which maybe readilyapplied to and will securely hold a refrigerator-tube while the latteris being inserted or removed from a barrel or other receptacle and asreadily released from the same.

The preferred embodiment of the invention is fully described in thefollowing specification, and the construction thereof is shown in thedrawings which accompany and form a part thereof. The construction thusset forth and described is, however, open to various changes andmodifications within the scope of the claims hereto appended.

In the drawings, Figure 1 is a side elevation of the machine employedfor holding the refrigerator-tubes while being inserted or removed froma receptacle, a beer-barrel being shown thereon to illustrate the mannerof supporting the same. Fig. 2 is longitudinal sectional view. Fig. 3 isa vertical section through a barrel, showing the improved tube in placetherein. Fig. f1 is a perspective View of the tube detached. Fig. 5 is adet-ail perspective View of the removable head. Figs. G and 7 are topplan views showing slightlymodified forms of heads. Fig. Sis a perspec-Serial No. 67,874. (No model.)

tive of the key employed for removing the head shown in Fig. 5. Fig. 9is a top plan view of the tube-holding device.

Similar numerals of reference designate corresponding parts in all thefigures of the drawings.

In the present case the refrigerator attachment is shown in connectionwith an ordinary beer-barrel; but it will be readily understood that itmay be employed in receptacles of various kinds. In the drawings thebarrel is designated by the numeral 10 and has the usual heads 11,provided with centrally-arranged screw threaded openings 12, into whichare screwed bushings 13, having annular flanges 1i, that bear againstthe outer faces of said heads. Extending across the barrel is therefrigerator-tube 15, the opposite ends of which iit snugly within thebushings 13. By referring particularly to Fig. 4L it will be seen thatthis tube is preferably cylindrical in form and has on its exteriorface, contiguous to one end, an annular flange 16 provided with notches17 in its peripheral edge. The end of the tube extending beyond thisflange has a plurality of openings 18, the purpose of which willhereinafter appear. The opposite end of the tube is provided withinternal threads 19 and is arranged to receive a head 20, the preferredform of which is shown in Fig. 5. This head comprises a cylindricalcollar 21, having external threads 22, which coact with the threads 19in the end of the tube. It is furthermore provided on its exterior facewith an annular flange 23,

having a pair of oppositely-disposed peripheral notches`24. A. wall 25extends across the collar, anda nipple 26 is secured therein, saidnipple having a passage-way 27 therethrough, which is closed by aturning-plug 28 or other suitable valve. It will thus be seen that whenthe headis screwed within the tube the wall 25 closes the end of saidtube and the flange extends over the end edge thereof. For the purposeof applying this head a key (illustrated in Fig. 8) is provided, saidkey comprising a shank 29, having at one end a handle 30 and at theother a ring 31, provided with proj ectinglu gs 32, arranged to engagein the notches 24: of the dange. By applying this device and rotating itin one direction or the other the head can be removed IOO or replaced.In Figs. 6 and 7 slightly-modified forms of head are shown,the samecollar 21 and fiange 23 being provided, but the notches 24 beinglocated, respectively,in the outer and inner faces of the collar. Itwill be obvious that aslightly-moditied form of wrench or operatingdevice will be necessary,in which case the lugs 32 will be locatedeither on the inner or outer faces of the ring 3l, as may be necessary.For the purpose of closing the open end of the tube a cap 33 isprovided, which fits over the projecting end of said tube and has anannular flange 34, that rests upon the integral fiange 16. Screws 35 orother suitable fasteners detachably connect this cap to the flange. Bythis means not only is the open end covered,`but the side openings 1Sare also closed.

The manner of applying the device will be perfectly evident. The head isfirst detached and a packing-gasket 36 is located upon the integralfiange 16. The tube is then inserted in the barrel and another gasket 37is applied to the end thereof, a small portion ot' which projects beyondthe bushing, after which the head `is inserted and screwed down tightly.As a result the integral flange ot' the tube will be drawn snuglyagainst the gasket 36, and a tight joint at both ends of the tube willbe insured. Furthermore, because of the internal threading of the tube/said threads will not interfere in the least with the removal orinsertion of the tube and will be protected from injury.

The refrigerator as thus described forms no part of the presentinvention, the novelty in this case residing in the machine for holdingthe tube while being inserted in or removed from a barrel or otherreceptacle. The mechanism illustrated in the accompanying drawings is atpresent considered preferable. A

Ahollow base-support 38 is secured in vertical position by a flange 39or other suitable means located at the lower edge thereof, said supportbeing provided at its upper end with a centering-ring 40, having a flatupper face 41, upon which are located positioning-lugs 42, as clearlyshown in Fig. 9. Within the support are arranged arms 43, pivoted attheir lower ends to lugs 44 and provided at their upper endsr withoffset outwardly-extending fingers 45, which are arranged to engage inopenings 4G, made for the purpose in the upper end of the support. Arock-shaft 47 is journaled in the bearings 48 in the lower portion ofthe support and has a projecting end 49, that carries an operating-lever50. Suitrable collars 51, secured to the shaft by setscrews 52, holdsaid shaft against longitudinal displacement. To the portion of theshaft located within the support is secured a crankarm 53, and the outerend of said crank-arm is pivoted to the lower end of an upright stem 54,the upper end of said stem being pivotally connected to links 55, thatare in turn pivoted to the upper ends of the arms 43. The preferredmanner of connecting the links 55 to the stem is shown in Fig. 2, saidstem being provided with an annular groove and the links having headswhich fit in said grooves. A nut 56, screwed upon the end of the stem,fit-s over the heads, and thus holds them in place, but permits of thenecessary pivotal movement. Y

Assuming the tube is to be inserted in a barrel, said tube is firstplaced upon the basesupport so that its integral flange will rest uponthe centering-ring and the projecting end adjacent thereto will belocated Within the upper end of the support. The tube is then rotateduntil the lugs upon the centering-ring engage in the notches of theintegral flange, whereupon the openings 18, above described, will alinewith the openings 46 in the upper end of the support. During thisoperation the arms 43 are in the position shown by dotted lines in Fig.2, and thus are entirely out of the way. After the tube has beenproperly positioned, however, the lever is thrown downwardly,consequently raising the stem and the links, which links Will force thearms apart, so that the fingers will engage in their respective socketsand necessarily pass through the openings in the tube alined therewith.By this means the tube is securely locked in place. The barrel is thenplaced upon the same and the head inserted in the manner alreadydescribed. Tofreniove the tube, the caps are first removed and thebarrel is placed upon the support in the manner shown in Figs. 1 and 2.Said tube is then locked and the barrel removed. By this means it willbe seen that a simple but very efficacious device is provided that willsecurely hold the tube in place and yet will readily release the samewhen desired. The elements are simple and are so constructed andarranged that there is little chance of their getting out of order; butshould they for any reason become deranged' or broken they arecompletely accessible for the purposes of repair or replacement.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-
